How to Perform a Power Cycle on a Nobi(ta) Light

This guide explains how to safely perform a power cycle on any Nobi light (Pendant, Ceiling, or Nobita), and when a power cycle can help.

5 min task

What

A power cycle means fully turning off the power to the Nobi light, waiting 60 seconds, and turning it back on.

Why

If your Nobi light isn’t working as expected or shows a technical alert, a power cycle can help restore normal function. It’s a simple first step to try before reaching out for support.

Use case

Each care home is set up differently. Some can cut power directly using room-specific circuit breakers, and others will need to unplug the power cable manually from the light. The way to perform a power cycle depends on which Nobi light you have.

Detailed Steps

1. Before you begin, check the power supply. 
   • The power supply will have a green light when it is connected. 
   • If there is no light, then the Nobi light isn't the problem. Instead, contact support. 

After confirming the Nobi light is connected to power, continue with the steps below. 

Choose the instructions which match the Nobi generation in the housing unit.

Gen 1 Nobi or Nobita:

If the Nobi light is a Gen 1 Nobi or Nobita, you should only:

1. Switch off the electricity.
2. Wait 60 seconds.
3. Turn the electricity back on.

Gen 2 Nobi Pendant:

1. Unplug the power cable from the top of the light.

2. Wait 60 seconds.

3. Plug the cable back into the center of the ceiling mount.

4. The light should now flash white briefly. This indicates that it is connected to the power.

Gen 2 Nobi Ceiling:

• Important note: If spacers (small white plastic parts) are installed between the light and the mount:
  1. Remove the spacers before taking the light down.
  2. Keep them safe – they must be put back when reinstalling the light.

1. Remove the light:
   1. Gently press the light upwards.
   2. Rotate the light a quarter turn (counterclockwise).
   3. Take the light down.

2. Check the cable. 

   • The end of the cable should be intact. If the pin is broken or missing like the image below, contact support.
     

   •  Below an image of the intact pin. If the pin is intact, please proceed with the next steps.
     

3. Wait 60 seconds.

4. Remount the light.

   1. Gently press the light upwards until you can gently rotate the light a quarter turn (clockwise) until it locks. 

   2. While pressing the light upwards, the light flashes for less than one second. This indicates the Nobi is connected to the power.

   3. Release gently – it should drop a few millimeters when connected correctly.
5. If no flash, retry once more:
   1. Remove the light
   2. Rotate it 180 degrees (half turn, like rotating a disc)
   3. Important note: If rotated 180 degrees, contact support to delete any drawn ignored zone on the device.
   4. Reinstall the spacers (if present) and mount the light again firmly.

You have now successfully performed a power cycle.
